This isn't the improved version of the Nine Halls-Eight Trigrams Array Formation maze she discovered underground when she was investigating the Bai Residence's tunnels in Changze County, is it?
The more Su Pan'er looked, the more startled she became, the more familiar it felt, until finally, she slowly closed her eyes and took a deep breath!
"I think, I know where this is!"
How could she not know where this was?
In the past, she, Qin Yi, and Old Cheng had been trapped in this formation for several days before they managed to crawl out!
And now, they were unexpectedly trapped inside it again—the most marvelous thing in this world lies in this coincidence!
"You know where this is? Then how do we get out?"
As soon as they heard Su Pan'er say she knew the location, Old Xue and Eleventh Uncle both perked up.
